Ansys 12

Geometry & Meshing

ANSYS has combined rich geometry and meshing techniques with its depth of knowledge and experience, resulting in integrated geometry and meshing solutions that share core libraries with other applications.
At ANSYS 12.0, geometry interfaces have been enhanced to import more information from CAD systems, including new data types such as line bodies for modeling beams, additional attributes such as colors and coordinate systems, and improved support for named selections created within the CAD systems. For pre-processing larger models, release 12.0 includes support for 64-bit operating systems and smart and selective updates of CAD parts.

Using the new MultiZone mesh method, a user can mesh complicated models with a pure hex mesh without the need for geometry decomposition. This brake rotor example can be meshed with a pure hex mesh in a single operation.

Multiphysics

ANSYS 12.0 expands the company’s industry-leading comprehensive multiphysics solutions. New features and enhancements are available for solving both direct and sequentially coupled multiphysics problems, and the ANSYS Workbench framework makes performing multiphysics simulations even faster than before.
   
Instability analysis for brake squeal At release 12.0, improvements to both the ANSYS Rigid Dynamics product and flexible dynamics capabilities in ANSYS Structural, ANSYS Mechanical and ANSYS Multiphysics software make the job of creating new mechanisms a faster one. A number of improvements to data and process handling increase ease of use for ANSYS Rigid Dynamics simulations. Flexible dynamics capabilities found in ANSYS Structural, ANSYS Mechanical and ANSYS Multiphysics products benefit at release 12.0 from robust component modal synthesis, or CMS.

Fluid Dynamics

ANSYS 12.0 introduces the full integration of its fluids products into ANSYS Workbench together with the capability to manage simulation workflows within the environment. This allows users — whether they use ANSYS CFX or ANSYS FLUENT software (or both) — to create, connect and re-use systems; perform automated parametric analyses; and seamlessly manage simulations using multiple physics.
   

Simulation results for the flow inside a cylinder in an internal-combustion engine ANSYS continues to make progress on basic core solver speed, a benefit to all users for all types of applications, steady or transient. A suite of cases that span the range of industrial applications has consistently shown increases in solver speed of 10 to 20 percent, or even more, for both ANSYS CFX and ANSYS FLUENT software.
The perennial goal of improving accuracy without sacrificing robustness motivated numerous developments, including new discretization options such as the bounded second-order option in ANSYS FLUENT and the iteratively-bounded high-resolution discretization scheme in ANSYS CFX. Being able to consistently use higher order discretization schemes means that users will see further increases in the accuracy of flow simulations without penalties in robustness.
   
Fuel injector model with close-ups of mesh and of vapor volume fraction contours at the injector surface Ease of use has been enhanced in various ways. Most noticeably, the ANSYS FLUENT user interface has taken a significant step forward by adopting a single-window interface paradigm, consistent with other applications integrated in ANSYS Workbench. For ANSYS CFX software, a host of improvements has been added to the graphical user interface (GUI). There is a completely new capability that allows users to customize GUI appearance, including the option to create additional input panels. These custom panels provide the ability to encapsulate best practices and common processes by giving the user control over GUI layout and required input.
Simulation Process & Data Management

In today’s global environment, the ongoing integration of simulation and product design makes effective collaboration and communication essential for successful product development. ANSYS Engineering Knowledge Manager (EKM) solutions are aimed at meeting simulation process and data management (SPDM) challenges faced by the simulation/CAE community. ANSYS EKM addresses issues such as how to better manage, share and re-use simulation data and how to better capture and re-use the engineering expertise that a simulation result represents.
ANSYS EKM is a truly scalable solution with three versions: ANSYS EKM Desktop, ANSYS EKM Workgroup and ANSYS EKM Enterprise. These versions provide entry points for the individual user, the workgroup or the entire enterprise, each with increasing capabilities and features.
ANSYS EKM Desktop is a single-user, local environment version of the ANSYS EKM product. It is available as part of ANSYS 12.0 and can be accessed via the ANSYS Workbench environment. ANSYS EKM Desktop is focused at meeting the challenge of “reusing existing simulations” by offering simulation data search, retrieval, and reporting features that can increase simulation productivity and efficiency.
Applications

ANSYS Emag - As the combined development teams from Ansoft and ANSYS set out to integrate the world-class Ansoft electronic design analysis (EDA) products into the ANSYS portfolio, ANSYS customers can benefit immediately from improved and extended electromagnetics capabilities in release 12.0. A new family of 3-D solid elements for low-frequency electromagnetic simulation is included in the 12.0 release of ANSYS Emag software. Solid elements (SOLID236 and SOLID237) are available for modeling magnetostatic, quasistatic time harmonic, and quasi-static time-transient magnetic fields. Users can apply this new element technology to most low-frequency electromagnetic applications, such as electric motors, solenoids, electromagnets and generators.
   
Nonlinear transient rotational test rig solved in the ANSYS Workbench environment using SOLID236, SOLID237 and the new stranded conductor option (TEAM24 benchmark) Explicit Dynamics - ANSYS has expended significant effort in the area of explicit dynamics for release 12.0 — including the addition of a new product that will make this technology accessible to users independent of their simulation experience. In addition, enhancements to both the ANSYS LS-DYNA and ANSYS AUTODYN products provide considerable benefits to their users. Newly introduced in ANSYS 12.0, ANSYS Explicit STR software is the first explicit dynamics product with a native ANSYS Workbench interface. It is based on the Lagrangian portion of the ANSYS AUTODYN product. The technology will appeal to those who require nonlinear dynamics simulation of solids, liquids, gases and their interactions. In addition, it will appeal to users who can benefit from the productivity provided by other applications integrated within the ANSYS Workbench environment. Those who have previous experience using ANSYS Workbench will find that they already know most of what is needed to use ANSYS Explicit STR.
